What they were not was stylish. Pierce-Arrows were conservatively shaped, seeming several model years behind the designs of competing brands such as Packard and Cadillac.
One thing Pierce-Arrow did well was advertise. That was in the days before television, when carmakers spent much of their advertising budgets on advertisements appearing in magazines. Pierce-Arrow's advertising people used quality illustrators for images. An interesting quirk was that the cars were often placed in the background of stylish, upscale people, helping to create a prestige image for a prestige car brand.

Treidler did many early ads, then in 1929 created images with the same theme as some of those early ones. At that point, Pierce-Arrow was harking back to its pre- Great War heyday.

I find the young lady more fetching than the car.
Can anyone identify who painted this?

An example of a Pierce-Arrow nostalgia advertisement. Note the small image of the first ad art, also probably by Foster.
I think the best-looking Pierce-Arrows were built around 1930.
Note the contra-jour coloring. Very nice.
Moderne was in vogue in 1934. Despite the Great Depression that was snuffing out Pierce-Arrow, upscale people are featured as usual.
